Abstract
PURPOSE: To reduce the operational force necessary to operate a piston valve by connecting a manual control handle and a servomotor, which operate a piston valve of a four-direction controlling valve, to the piston valve through a modeling unit with a power-increasing function.
CONSTITUTION: A manual control handle 6 is connected to a rotor 4 via clutch 5, while a servomotor 8 to the rotor 4 via a clutch 7. The rotor 4 gives input to a modeling unit 3, which moves a piston 1 in a four-direction control valve 2. Thus, a small force given to the modeling unit 3 is enlarged. Accordingly, the manual control handle 6 can be operated easily, while a low-output servomotor 8 can be adopted, thus the manufacturing cost can be reduced.
